Abstract

An apparatus for monitoring the marking of a recorded signal includes a data store containing marking information and a code selector for selecting any one of three orthogonal codes for marking the recorded signal and a demodulator for demodulating the marked signal and comparing this with the orthogonal codes. The demodulated marked signals are then fed to matched filters and accumulators wherein the marking process may be repeated dependent upon the value of the accumulation.
